Desktop freezes since -14 kernel in Gutsy when using Skype

[Matthew Tighe]

That's it really. Skype is using the bluetooth subsystem for the headset. Here's /var/log/messages from before and following the freeze:

The only think interesting there is "Oct 10 11:13:58 localhost kernel: [ 7736.968000] rtc: lost 2 interrupts".

It happened earlier in the morning, but without the rtc: lost 2 interrupts statement.

Opened a more generic version of this as Skype is not actually involved. It is happening w/o Skype running
